Sr. Sales Engineer

Fontaine Modification Company

As a part of the global industrial organization Marmon Holdings—which is backed by Berkshire Hathaway—you’ll be doing things that matter, leading at every level, and winning a better way. We’re committed to making a positive impact on the world, providing you with diverse learning and working opportunities, and fostering a culture where everyone’s empowered to be their best.

Fontaine Modification focuses on the design and manufacturing of innovative solutions for heavy truck manufacturers, dealers, and commercial truck users worldwide. We fill the niche between what OEM truck chassis builders can produce in their manufacturing plants and what the market needs for a wide variety of fleet and vocational truck applications. Fontaine’s long history of providing innovative and custom-engineered solutions in an environment of integrity, customer responsiveness, quality products, and superior workmanship has made us a recognized leader in the industry.

Fontaine Modification Company is seeking a Sr. Sales Engineer to support and execute the quote-to-delivery process for assigned customer opportunities. This role translates customer, dealer, OEM, fleet, body company, and vocational application requirements into accurate, executable commercial proposals while coordinating closely with sales leadership, regional sales managers, engineering, purchasing, production, and operations.

The Sr. Sales Engineer may support customer communication and relationship management, but the primary purpose of the role is commercial and technical execution. The position owns the details required to move an opportunity from initial request through quotation, order readiness, production coordination, issue resolution, and delivery support.

Success in this role requires disciplined follow-up, technical learning agility, customer responsiveness, attention to detail, commercial judgment, and the ability to coordinate across multiple internal functions to ensure Fontaine delivers solutions that are properly scoped, priced, documented, and executable. 

This position may be based out of either our Dallas, TX or Charlotte, NC office.
